Description
HOW TO EDIT WEIGHTS WITH UNDO/REDO:
"Interactive" Edits: For multiple weight editing operations that need to be grouped into a single transaction, like dragging a slider or dragging a brush, you must call:
BeginChange()
ApplyWeightEditsWithoutTransaction() (this may be called multiple times)
EndChange() All the edits are stored into the "ActiveChange" and applied as a single transaction in EndChange(). Deformations and vertex colors will be updated throughout the duration of the change.
